This invention relates to a corner joint for the Vertical corners of a room, or for the corners formed by the ceiling or floor and vertical side walls of a room.

It is an object of this invention to provide a joint for the converging side walls of a room or a jointl for the junction point between the ceiling or oor and the side walls of a room, which will prevent opening up and forming of a crack at the junction point between the side walls in the corner of the room or the junction point between the ceiling or floor and one of the side Walls, and thus preventing the necessity of having to use a molding at the junction point to cover the seam formed between the two converging sheeting members forming the interior surface of a room.

It is another object in this invention to provide a corner structure for a room in a building which will cause the ceiling or wall portions of the room to remain in xed position and prevent seams or cracks forming between the junction points of the sheet members forming the walls of the room.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which Figure 1 is an exploded isometric view of the parts making up the joint.

Figure 2 is a horizontal sectional viewtaken through the two wall portions forming a projecting corner in a room.

Figure 3 is a vertical sectional view taken through the upper portion of a room and through the ceiling covering and the wall covering or it can be a horizontal sectional view taken through the corner of'a room and cutting through the two wall portions forming the inside covering of the walls of the room.

Figure 4 is a sectional view taken along the line 4-4 in Figure 3.

Referring more specically to the drawings, the numeral I indicates a corner upright or a horizontal member disposed above the ceiling of the room, while numeral II indicates another timber which may be a corner post or a horizontal member disposed at the top of the wall of a room. If these numbers I0 and II represent corner posts, then the plywood member is adapted to be placed in vertical position and secured to these two timbers I0 and Il. The plywood member is composed of a plurality of sheets of veneer I2 and I3and shaped wood members I5 and I6. The members I2, I3, I5 and I6 are securely glued 2 claims. (01.5 209-92 `together in a suitable: press to form a right angle member of any suitable length, which extends from one wall oi the room to the other when used as a joint between the ceiling and one of the walls, and also extends from the floor to the ceiling if used as a vertical corner joint member.-

This plywood member composed of veneers I2 and I3 and shaped wood strips I5 and I6, is fastened to framing members I0 and II by nails Il, or by any other suitable fastening agent, except glue or other permanent adhesive.`

After this plywood member is placed in position, whether it be in vertical or horizontal position, the sheeting members I8 and I9, which form the wall or ceiling covering, are placed in position. Before placing the sheeting members I8 and I9 in position, however, the exposed contact surfaces of the plywood member are covered with a suitable adhesive 20, such as glue, and then the sheeting members I8 and I9 are placed in position, and are suitably secured along the walls, either by gluing or by nailing or otherwise, and thus a secure joint is provided, which, due to the gluing of the Wallboards I8 and I9 to the common plywood member, will provide a homogeneous structure, which will cause the members I8 and I9 to become an integral part of the plywood member and, therefore, if the timbers I and Il should tend to separate, the plywood member will have a tendency to prevent the separation of members I8 and I9.

It is thus seen that there has been provided a building joint adapted to be used in the placing ofthe sheeting covering over the interior surfaces of the walls of any room and placing the ceiling or iloor in position, and which provides a corner structure which holds the sheeting members in proper position and prevents separation at their junction point to provide an opening up and causing ugly cracks which heretofore it has been necessary to obscure by placing a molding member such as a quarter-round thereover.

Although the angle member to be composed of two strips of veneer and two shaped wood strips, and of a right angular nature have been shown and described, it is to be understood that if made of wood, the angular member may have more layers than shown, or it may be of an angularity other than that of a right angle to suit conditions, or it may be made of metal, plastic, textile or other suitable material.

In the drawings and specifications, there has been set forth a preferred embodiment of the in 2. A corner joint `for Wall boardliningsffor 9.V
